After some investigation, it can basically be determined that Wu Yongjun is the murderer of Jin Yingqiu, so that Qin Cang's speculation has been further confirmed, so the next thing that needs to be done is to find the person who may be the murderer in Wu Yongjun's circle.

For this direction of investigation, Qin Cang has long considered it, he called the big guys together for a meeting, and told them that the target of the investigation should be around Wu Yongjun and know him, but the relationship is not how familiar and intimate the group of people are, and the other party should be the type with a strong sense of justice, on this basis, it also needs to have the characteristics of a relatively weak personality, not enough courage and courage.

Tang Guo originally wanted to ask Qin Cang why, but after thinking about it, she didn't need to ask herself, she understood that it was actually very simple, the serial scheme of this case was actually a reason for the latter to kill the previous person. Just like Jin Yingqiu killed Mei Qingzhuo because Mei Qingzhuo harmed her son, so she was willing to go to great lengths to retaliate back, and Jin Yingqiu was killed by Wu Yongjun, it is estimated that nine times out of ten it was caused by the superstitious so-called "disaster star", which made Wu Yongjun kill a strange woman who had no grievances with her. So what is the biggest stain on Wu Yongjun's body? Judging from the fact that someone can be moved to kill someone, it is obvious that it will not be a reason for a small fight, and it may not be so easy to find someone who has a personal vendetta like Jin Yingqiu and Mei Qingzhuo, so there is a better choice, that is, let the other party not regard killing Wu Yongjun as a crime.

At this time, it seems to be a more reasonable assumption to give such a person a reason that seems more reasonable, so that the killing of Wu Yongjun has changed from killing people to eliminating violence and harming the people.

And when the other party implemented it, it was obvious that they did not have such a strong determination, so there was a situation of retreating halfway, and they had to be personally ended by the mastermind behind the scenes, which was never intended to be exposed, that is, the scene they faced in the end.

After having a clear goal, the investigation became much smoother, and soon they had a harvest, and three targets around Wu Yongjun were determined to be more in line with Qin Cang's requirements, and these three people were arranged around them to secretly watch people, and these people were also under Qin Cang's application, all of them were served by the serious crime team itself, as well as the newcomer police officers who had just joined other departments of the Public Security Bureau, among these people, one of them who had worked in the Public Security Bureau for the longest time was no more than half a year, including interns, Although such a decision seems a bit risky, according to Qin Cang's requirements, all the personnel in charge of stalking need to be face-to-face, and they can't be easily recognized as internal staff of the Public Security Bureau, so that's the only way.

And Qin Cang himself, among the three goals, also made a comparative choice, and finally decided to personally participate in the stalking work of one of them with Tang Guo, this person is named Wu Datong, in fact, Wu Yongjun's nephew, but he is not an immediate family, and there are several turns in the middle, this Wu Datong is only 24 years old this year, he is a little otaku who is unemployed at home, and his biggest hobby is to play games, whether it is a stand-alone game or an online game, especially the kind of bloody violence, killing and killing, It seems to be the type of revenge that is more happy.

The reason for choosing this person, Qin Cang also said very clearly.

"A person who tends to choose this type of game and indulge in it in the world of online and games is often a person who also has this yearning in that life, but lacks courage, so he finds solace for himself in the fantasy world." Qin Cang explained his choice to Tang Guo like this.

Not only did he choose this person named Wu Datong to keep an eye on, but he also stared at it in a particularly high-profile manner, and the serious crime team came forward to borrow a broken van from elsewhere, and a very eye-catching advertising board was set up on the outside of the body, with the words "XX Fur Anti-Season Dumping" written on it, as well as some bells and whistles fur patterns, as if it was an advertising car that had been driving all over the street for promotional purposes before, Qin Cang parked the car in the most favorable surveillance position around Wu Datong's residence, and then began his and Tang Guo's daily stalking.

After the ambush, three days passed in a blink of an eye, there was no movement, Wu Datong did not say that there was any normal or unusual behavior, and he even went out very little, and he only went out twice in three days, once he went downstairs to express delivery, once he went downstairs to buy food outside, and at other times he didn't go out at all, the person was listless, as if he had lost his soul, and at the same time he seemed to have a little nervousness of being a soldier, obviously walking well, but he would suddenly turn back to see if there was anyone behind him.

"It should be him." His words and actions made Qin Cang feel much more determined.

Tang Guo didn't speak, she was very nervous in her heart, because she understood that it would not be long before the answer to Qin Cang's guess was correct or not.

Sure enough, on the evening of the fifth day, Qin Cang and Tang Guo happened to take turns to watch on the night shift, and not long after the two of them arrived, Qin Cang suddenly noticed something unusual, and reached out to push Tang Guo to make her pay attention.

"At nine o'clock, look carefully at the delivery man in the delivery uniform of the delivery company." He said.

Tang Guo hurriedly cast his attention over, and sure enough, he saw a person who looked like a food delivery person walking in the direction of Wu Datong's house, at first glance, there was nothing, and there was no shortage of food delivery people in this neighborhood these days, but after a closer look, I felt that something was not quite right, this food delivery person walked a little too steadily, and the uniform looked new on the body, without a little dusty appearance, and the feeling of the food delivery person she had seen on weekdays was not the same at all, This person was still carefully paying attention to the surrounding situation while walking, the sky was already dark, but he was still wearing a peaked cap with a lower brim, and then took a closer look, he felt that this person's size and posture were also somewhat familiar, Tang Guo's heart sank suddenly, and he realized that the real time to close the net had come, and he had become the luckier one in Qin Cang's mouth, and he didn't need to be pushed to the cusp to act as any bait, and at the same time, Qin Cang's previous speculation was also equivalent to being confirmed.

"Do you want to keep up now?" Tang Guo asked.

Qin Cang shook his head: "No, wait a minute, it's bad early, it's bad late, it must be just right." ”

Tang Guo was so nervous in his heart that he almost couldn't sit still, and he felt that every minute and every second was frightened, until Qin Cang told her, and also told the other colleagues who were surrounding on the walkie-talkie that it was time to start acting, so everyone quickly got out of the car and rushed towards Wu Datong's residence quickly and quietly.

Wu Datong's residence is the kind of relatively old house, when he comes to the door of his house, you can see a neighbor on the left and right, the door is full of all kinds of small advertisements, it is obvious that no one lives, the door of Wu Datong's residence is also the kind of old-fashioned anti-theft door, Qin Cang came to the door quietly, avoided the position of the door mirror, put his ear on it and listened, the TV inside was very loud, and the sound of the program could be heard through the door, so he gestured to the technical unlocker waiting on the platform under the stairs, The other party quickly ran up, moved gently, and quietly began to flip the lock, and it didn't take much effort to open the lock.

Qin Cang cautiously opened the door and looked inside, there was no one in the small living room, the TV was on, there were advertisements without any nutrition, and there were faint whimpering sounds coming from the house. Qin Cang no longer hesitated, pulled out his gun and opened the door and rushed in, Tang Guo followed, and after entering the door, he went straight to the inner bedroom with a very purposeful purpose, and kicked open the closed door of the bedroom.

The bedroom area is not large, and there are two people in it, one is Wu Datong who is tied like a zongzi, and the other is Yan Lifu who is standing next to Wu Datong wearing the clothes of a food delivery person.

The other people who followed behind Qin Cang were very surprised to see Yan Lifu standing next to Wu Datong, holding a gun in his hand, although they were all newcomers and had not dealt with Yan Lifu directly, but most of them were the same as Tang Guo, they had heard of Yan Lifu's name in the criminal police world, and they also regretted his resignation and career change, they probably couldn't imagine that they would see this famous criminal policeman who was once famous in such a situation.

Yan Lifu was also taken aback by the sudden intrusion of these people, but he quickly calmed down, his face returned to normal, and he even nodded to Qin Cang and Tang Guo with a little smile and said hello. Wu Datong on the side, who was originally just a small whimper, trembling all over, but this time when he saw that the savior came to the door, he also struggled desperately, and his gagged mouth let out a cry for help.

"If I were you, I wouldn't pick such a time to toss hard, if you don't struggle, we can see that you are controlled by him, the toss is big, beware that he is angry and shoots you directly, no matter how much we want to save you, we can't be as fast as a bullet." Qin Cang frowned, glanced at Fang Datong, and said to him.

Fang Datong obviously heard his words, and when he heard the words, he immediately felt as if he had been pointed at by someone, and he didn't dare to move, as if he didn't even dare to take a breath.

"As for you, do you feel particularly regretful? It's better not to resign at the beginning, if you don't resign, you can still find an excuse now, saying that you found the suspect and controlled him, or that he resisted stubbornly and was finally killed by you, maybe you can be considered meritorious. Qin Cang said to Yan Lifu with sarcasm.
